/* ab.css — page layer for /activity-book-maker/. The shell (header, controls, buttons, explainer,
   footer) is /assets/polyatic.css; this adds the cutting-mat stage with the printed page on it, as on
   /name-tracing-worksheet/ and /maze-generator/, plus the page flipper and the strip of little pages.
   The paper is white in both themes, because that is what prints. */
